A spring scale is used to weight beans on an elevator. How will the readings for a given amount of beans change when the elevator is (a) going down with constant velocity,(b) moving with a constant downward acceleration less than g, (c) moving upward with a constant velocity, (d) accelerating upward with an acceleration a. What happens in above cases if we use a beam balance.
